A methodology for development of a query system for allowing to different type users achieve knowledge about olive crop and its environmental support in the province of Granada, Spain, is proposed. The information system is flexible and based on fuzzy relational databases, for allowing interactive querying. The main issues handled by this model are those referred to uncertain and imprecise knowledge, as environmental and crop data, spatial and concrete data representation, and crop outcome and scientific-experimental character data join.
Key words: Olive crop, flexible query, fuzzy relational databases, geographical information systems.
